IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 135,363, dated January23, 1873.

To all whom it may concern:

Be itknown that I, EDWIN REESE, of Enta-w, in the county of Greene andState of Alabama, have invented ,an Improved Plow, of which thefollowingis a specification:

The invention relates to self sharpening plows; and consists in apeculiar construction of land-side, by which the point and edge of shareare allowed, in a certain and uniform manner, to wear upon both upperand lower sides, so as to retain the same angle of edge As the land-sideG of a common plow abuts against the bottom of the share, it takes aportion of the wear from friction, and does not allow the point to beabraded horizontally on its bottom, butcompels the abrasion to take anupward turn,- and soon dubs it off. This is the condition iu'which'wefind a share when removed from the plow in order to be resharpened. Toavoid this difficulty I form the landside of two pieces, D E, and leavea vacant space where the part 0 of an ordinary landside is placed. Thisgives the bottom of point and whole edge of share an opportunity to wearoft in a horizontal plane, and thus maintain each at a constant angleand always sharp. Hence, with my invention, after a steel share is onceattached to a plow it becomes selfsharpening, and never requires removaluntil worn down so as to be inthe same plane with the bottom of piece Eand mold-board A. In order to give to the plow the support required fromthe land-side the part D is sloped at d, and has a flat surface, d,which rests on the bottom of the furrow. The part E of land-side has ariser, e, which fits into a recess of the "mold-board, and is boltedthereto. The ends d e of the two parts of land-side form a socket-joint,and allow D to be lowered or elevated at any time to cause the plow torun squarely and on a level. H is a rod, flattened and provided with aslot or several perforations, h, at the upper end. By bringing one andanother of these perforations about the holdingscrew h of standard GthepartD of land-side may always be fastened at any desired adjustment.

Of course 1 am aware that self-sharpening shares and points are not new,broadly, and I only intend to claim my particular construe tion ofland-side, by which I can more conveniently, easily, and eflectuallymake them selfsharpening.

Having thusdescribed my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A bottom concaved landside, having the rear section D jointed to a fixedsection, E, for the purpose of giving angular adjustment to the rearsection of land side as the bottom of share wears, and thus preserve thecuttingedge of said share always at or about the true angle.
